New article on mapping risks from arsenic exposure via dust particles

The inhabitants of developing countries like Pakistan have been exposed to trace metal contamination via different pathways. In sequence to our last article on human health risks from exposure to trace metal contamination of drinking water sources under the “Mapping human health risks from exposure to contaminants in developing countries” project, my colleagues and I have assessed the risks from arsenic exposure via dust particles in Pakistan in a recent study. The results have been published in Ecotoxicology and Environmental Safety (Impact Factor: 2.762) 126 : 219-227.

Spatial variation of the mean arsenic (As) concentration in the human nail samples and associated risks of exposure (concentrations exceeding USEPA (2001) allowable limit of 1 ppm). The figure has been adopted from the article

The results indicated a higher level of arsenic concentration in dust and human nail samples from the flat and low lying areas than the mountainous areas. The variability in arsenic concentrations were associated with altitude (23%), soil carbonate carbon density (33%), soil organic carbon density (49%) and population density (25%). Inhabitants, particularly children of densely populated areas were shown to be at high risk from arsenic exposure via dust particles, continue reading:
